There are exactly twenty-seven straight lines on a smooth cubic surface, [2] which give a basis of the fundamental representation of Lie algebra. [ 3 ] [ 4 ] The unique simple formally real Jordan algebra , the exceptional Jordan algebra of self-adjoint 3 by 3 matrices of quaternions , is 27-dimensional; [ 5 ] its automorphism group is the 52 ...
m is a divisor of n (also called m divides n, or n is divisible by m) if all prime factors of m have at least the same multiplicity in n. The divisors of n are all products of some or all prime factors of n (including the empty product 1 of no prime factors). The number of divisors can be computed by increasing all multiplicities by 1 and then ...
127 (one hundred [and] twenty-seven) is the natural number following 126 and preceding 128. It is also a prime number. It is also a prime number. In mathematics
It has as factors 1, 7, 13, 19, 91, 133, 247, and 1729. [2] It is the third Carmichael number, [3] and the first Chernick–Carmichael number. [a] Furthermore, it is the first in the family of absolute Euler pseudoprimes, a subset of Carmichael numbers. [7] 1729 is divisible by 19, the sum of its digits, making it a harshad number in base 10. [8]
26 is the seventh discrete semiprime [1] and the fifth with 2 as the lowest non-unitary factor thus of the form (2.q), where q is a higher prime. 26 is the smallest even number n such that both n + 1 and n − 1 are composite .
In pursuit of its third straight promotion, Wrexham splashed some cash at League One rival Reading to secure the services of striker Sam Smith. The Welsh club owned by actors Ryan Reynolds and Rob ...
In a vigesimal place system, twenty individual numerals (or digit symbols) are used, ten more than in the decimal system. One modern method of finding the extra needed symbols is to write ten as the letter A, or A 20, where the 20 means base 20, to write nineteen as J 20, and the numbers between with the corresponding letters of the alphabet.
Factors such as poor sleep, stress, irregular eating habits, excessive exercise and environmental toxins can aggravate vata, leading to painful menstruation. In some cases, dysmenorrhea may also ...
